If you are using a ribbon remove it and perform a calibration, hold down feed key for 2 seconds as you power on, release key and wait for it to complete its calibration, when it has stopped shifting labels (wait for 10 secs to be sure) HIT THE FEED KEY to exit dump mode. If it has successfully calibrated it will feed a label each time you hit feed key. Re-install ribbon, make sure ribbon is pushed formly onto drive sprockets and then re-run the calibration..

If this does not fix problem. download firmware to latest version. This will automatically reset printer to factory default condition.
